[Drug therapy for glaucoma].

Drug therapy for glaucoma is based on lowering of intraocular pressure regardless of the pressure level, at which the disease has been diagnosed. Earlier it was empirically clear that in disease cases involving a high pressure, drug therapy will slow down the advancement of the disease. During the last ten years scientific evidence has accumulated indicating that a disease with normal pressure is also worth treating. Drug therapy can also postpone the onset of glaucoma at a time when intraocular pressure is high, yet without structural or functional damage.
